Hello @misbahsuhail123 ,

I’ve been doing some tests and it’s working OK for me. Don’t you see the arm moving after executing the script?

Thanks Alberto, problem solved i think when internet
speed is slow or by switching b/w units the problem solved. i just restart the unit and it did worked. Thanks alot.

Hi Alberto, it ran only once and then whenever i tried it again, i am unable to solve it, gave two commands:

  1. roslaunch smart_grasp_mod_moveit_config smart_grasping_planning_execution.launch
  2. python basic_concepts.py
    Everything is seen fine in Rviz environment.
    smart_motion

But the arm didnot move as shown in image:
Kindly help in sorting out this problem.
Thanks
